State of Indiana, have invented certain'new and useful Improvements Acetylene-Gas llowlng 1s..a specifi- Torches, of which the cation.

The o-bject of my said invention is to pro- 'vide an acetylene torch, or a torch adapted to operatively connect with an acetylene, gas tank, whereby. such torch may be fed directly from sucha tank and used for all purposes for which torches are commonly provided. It is especially adapted for use as a part of the tool equipment of such motor vehicles as are provided with an acetylene lighting system. Such use of acetylene gas has heretofore been found impracticable for various such as the ditficulty of securing a reasons, to renderthe gas practically to make it' in any degree permanent or practical. ated also commonly serves to destroy the burners provided, and renders them quickly useless for any practical purposes.

My said invention consists, jtherefore, in

an improved form of acetylenetorch burner,

which these difficulties are assured, all as will fully described and or fixture, by overcome and success be hereinafter more claimed.

Referring to the accompanying drawings,

which are made a part hereof and on which similar reference characters indicate similar parts: Figure 1 is a'view showing-one end of an acetylene gas tank with a hose connection thereto and one. of torch. attachments thereon, Fig. 2, an end view of said torch attachment, and Fig. 3, a longitudinal section through the same.

In said drawings the portions marked A represent the gas-tank, B the hose, and C the burner, or torch attachment, said attachmentcomprising a metal body having a rear chamber 10 formed internally screw threaded, or otherwise appropriately formedfor connection with the hose B. Its opposite or front end is formed with an elongated chamber 11 of uniform diameter connected with chamber 10 by means of a very small perforation 12 through an otherwise solid partition between said chambers '10 United States, residing at the county-of Marion and discharge; ends being just in front 1 of ;per'- iteration .12, The outer. end of said burner The intense heat gener-' my improved f-onarrnr. n. s in-nun, Oman-masons, IN IANA; Ass'renon ro' warm s -assure mmanaroms,-rmra u; 'a conrona'rron or mmam.

at 1 an angle toward the front ot the torch fixture nto the Innerendof chamber .l1,-.their isforn ed with a cup-shaped combustion chamber 15 of approximately double the diameter-of the chamber 11. The metal of. the body Cis cut out from point 16 to point 17, as shown, so that the metal surrounding the greater lengthof chamber 11 is comparatively thin, which permits the rapid or free radiation ofthe heat and preserves this part of the burner from dest'ruc-' tion. V

;In operation, the torch fixture is attached to the hose B and the hose B' attached to the acetylene tank A, as shown in Fig. 1.

The gas is then turned on and rushes through hose B into chamber 10 and through the small perforation 12, under considerable pressure, into chamber 11 and causes a suction through the air ducts 1 which, as shown, are many times the area of the perforation 12 and thus admit comparatively large quantities of air which mixes with the acetylene "gas in chamber 11.

Said chamber 11, .because of its elongated form, confines the gas and air until the elements have commingled sufiicientl to form a combustible mixture which is ignited in and 111.1: asaasn" 1...,1 throughithe Several s des'of the chamber-from thejoutside the chamber 15. The expansion of the mixture into chamber 15 reduces the pressure sufiiciently so that said mixture will ignite and burn with a steady, permanent and practically useful flame. The walls of said chamber also protect the flame so that it cannot be readily extinguished except by an intentional efiort. Such a device is of great convenience as a part of the equipment of a motor vehicle, the hose B being readily connected with the ever ready supply of acety lene gas in the acetylene tank, which is a part 50f the vehicle equipment. The hose may be of such length as to enable such.

torch to be used around any part of the vehicle, thus providing a torch of a character 'that is' especially eflicient as well as convenient for the purpose.

Having thus fully described m said invention, what I claim as new an desire to secure by Letters Patent, is:

1-. An acetylene torch burner comprising a unitary body formed with apipe connectionl and receiving chamber at onelend, an elongated mixing chamber. at its other end, a'part-ition. betweensaid receiving chamberand said miximehamber within small gas inlet port leading therethrough;'v'intousaidmixing chamber, air ducts throughthe alls of said body leading into said mixing wa an an" inlet @hambe} anus "said;
